Play select games from the ST Math fifth grade curriculum. Concepts include volume, order of operations, and more.

Find volume of rectangular prisms.

- Develop concept of volume measurement using cubic units.
- Levels begin with simple 3-D objects composed of cubic units, then advance to finding volume using dimensions of rectangular prisms.
- Use a multiplication formula for finding volume.

Use parentheses in expressions to build visual models.

- Understand the use of parentheses in determining order of operations.
- Given a visual model, determine the order of operations for generating the model.
- Levels begin with two-step expressions using addition and multiplication, then progress to multi-step operations.

Develop strategies for adding fractions with unlike denominators.

- Use visual fraction models to create common denominators for adding fractions with unlike denominators.
- Levels begin with modeling sums of fractions with like denominators, then advance to creating visual models using both unlike denominators for partitioning an area model.

Plot points on a coordinate plane and write ordered pairs.

- Plot points in a coordinate plane given an ordered pair.
- Write ordered pairs given a point on a coordinate plane.
- Feedback animates the role of ordered pairs in plotting points.

Estimate products of fractions and whole numbers on a number line.

- Develop concepts and strategies for multiplying fractions by whole numbers and whole numbers by fractions.
- Multiplication of a fraction by a whole number can be modeled by iterating a given fraction.
- Multiplying a whole number by a fraction can be modeled by dividing the whole number by denominator and multiplying by numerator.

Convert within customary units of volume

- Convert within customary units of volume: Gallons, Quarts, Pints, Cups.
- Levels begin with simple conversions of 1 larger unit to smaller units, then advance to converting fractional amounts of a larger unit to smaller units ( 1 ½ gallons = __ cups).

Count and match sets of up to 10 objects.

- Develop counting strategies such as 1:1 correspondence and cardinality.
- Levels begin by just clicking on given objects, then progress to selecting equivalent number of squares in the ground.
- As the levels transition, students internalize strategies and connect numerals to the counting sequence.

Develop addition concepts by finding the total number of blocks.

- Add blocks at the start (left side) to the blocks in the middle by selecting the total number of blocks at the end (right side).
- Develop and apply strategies for solving visual addition problems.
- Levels start with sums ≤ 5 by adding up to 2 more blocks and transition to sums up to 10.
